DC/DC converter modules for high power applications

Artesyn has added three 50V DC/DC converter modules to it portfolio in a move to support what it sees as the rapidly growing application of GaN and high voltage LDMOS technology to provide increased power density and higher efficiency.

The AVE450, AVE500 and ADH700 modules are rated at 450W, 500W and 700W respectively. Each features a high power density open frame design in a telecom industry-standard half-brick format, with an optional aluminum baseplate for thermal performance.

According to the company, the AVE450 series offers a typical efficiency greater than 95% and can deliver up to 10A. Meanwhile, the ADH700 and AVE500 series have a typical efficiency in excess of 94.8% and deliver up to 14A.

The modules offer an output voltage trim range from 25V to 57V, with features such as remote control, low ripple and noise; input under voltage lockout, output over current protection, output over voltage protection, and over temperature protection.

All models can operate between -40 and 85°C and operate at full power at baseplate temperatures of up to 100°C.
